Title: Improvements in or relating to hot water circulation heating systems
Inventor: DEAN GEORGE THEODORE KENNETH
IPC: F24D3/10
Filed: 1964-04-20
Abstract: 1,116,411. Central heating systems. ANDREWS-WEATHERFOIL Ltd. 14 July, 1965 [20 April, 1964], No. 16219/64. Heading F4U. In a central heating system, of the type disclosed in Specification 967,958, but wherein the feed line 19 with the non-return valve 21 leads into the expansion pipe 12 from the boiler and the heat distribution units (not shown), the major portion 10 of the contraction compensation vessel is not heated, but is connected at the top to a secondary vessel 22 containing a thermostatically controlled immersion heater 25, which keeps a small portion of the water at a hotter temperature than the remainder in the major portion 10 of the contraction compensation vessel. On expansion of water in the central heating system out of expansion pipe 12, past pressurized valve 17 and into feed tank 18, followed by subsequent contraction on cooling of the remaining water in the system, it is the hotter water from vessel 22 which flashes into steam at the top of the major portion 10 of the contraction compensation vessel, preventing air locks from forming in the central heating system. A float valve 26 (Fig. 2, not shown) or a thermostatically operated valve (Fig. 5, not shown) in branch 11 prevents thermo-siphoning of colder water from the bottom of the major portion 10 of the contraction compensation vessel up expansion pipe 12 and through branch 11 to the top of the vessel, but permits water from the feed line 19 to flow into the top of the vessel, on emptying of the top of the vessel caused by condensation of the flashed steam on protracted cooling of the heating system. A further float control connection 27 between the major portion 10 of the contraction compensation vessel and the secondary vessel 22 is for use in filling the latter. In modifications, the vessel 22 may be connected to the major portion 10 of the contraction compensation vessel by a single connection to the upper part of the latter (Fig. 3, not shown) or the vessel 22 may constitute a separate compartment in the top of the vessel 10 (Fig. 4, not shown.)

Title: Steaming machine
IPC: A23N17/00
Filed: 1960-05-10
Abstract: 884,884. Steam - cooking apparatus. STARKE, W. May 10, 1960 [May 29, 1959; March 7, 1960], No.116417/60. Class 28 (1). A steaming machine with an oblique steaming chamber 1 has a grating 9 and a water removal chamber, steam being fed to the latter so that it passes through the grating to the material to be treated. As shown, potatoes are fed, e.g. by elevator 6, into a vertical part 2 above steaming chamber 1. The bar grating 9 is mounted on cross-supports 8 on the base 7 of chamber 1 to form with end plates 10, 11 the water removal chamber from which the water flows into a chamber 18. A steam pipe 12 with nozzles 13 feeds steam to the top end of the water removal chamber. The softboiled potatoes are removed through pipe 16 by a screw 14. In operation, raw potatoes are placed in the apparatus up to an observation window 3 and steam is fed in through nozzles 13 so that it is distributed through the potatoes, the condensate being removed through grating 9 to collect in chamber 18. Chamber 18 contains a pipe 20 terminating in a valve seating 19 on which rests a float 22 guided by guides 21 and of such a weight that it forms a steamtight seal until a predetermined liquid level is reached. In a modification, Fig. 4, a second grating 23 is provided which with a plate 24 forms a second water removal chamber. In a further modification, Fig. 7, water is discharged from the water collecting chamber 33 through a coiled pipe 36 with an inlet near the base of the chamber and an outlet 38 level with the top of the coil.

Title: Improvements in or relating to the manufacture of carbon black by the electrothermaldecomposition of liquid hydrocarbons
IPC: C09C1/48
Filed: 1937-06-14
Abstract: In the manufacture of carbon black and gaseous products from liquid hydrocarbons by means of a submerged A.C. arc, the arc current is maintained constant to within 10 per cent and preferably within 2-5 per cent by means of resonant capacitative and inductive circuits <PICT:0497234/III/1> <PICT:0497234/III/2> <PICT:0497234/III/3> connected to the constant voltage A.C. supply or by a constant current transformer or constant current reactor.  By this means an improved quality of black is obtained.  The current may be stabilized by using known resonant circuit means such as the "T resonating circuit" in Fig. 1 in which constant voltage A.C. from a transformer 10 is converted to constant current A.C. by two inductances 7, 8 of equal resistance and a shunt condenser 9 having an impedance equal to that of one of the inductances at supply frequency.  Alternatively, a three-phase arrangement may be used in which an inductance and condenser in series are connected between each of the supply terminals and the output is taken to three pairs of arc electrodes from the junction points between the inductances and condensers which have equal impedance values.  The "monocyclic square" connection, Fig. 6, may be used whereby constant voltage A.C. is converted to constant current A.C. by a bridge connection of inductances 14 and condensers 12 of equal impedance.  This circuit may supply two arcs 4, 4a having different voltage settings so that only one operates normally and the other operates under emergency conditions when the first arc fails.  Operation of the emergency arc 4a, Fig. 6, may operate an indicator such as an ammeter, or cause tripping of a switch 22, 23 to open the supply circuit.  In a further arrangement, Fig. 7, a constant current transformer is used to supply the arc 4, the primary 8 being movable and the attractive force between it and the secondary 7 being balanced by a weight W whereby the secondary current is maintained constant. In place of the transformer 7, 8, a constant current reactor of similar construction and operation may be connected in series in the arc circuit to maintain the current constant.  The arrangements are applicable to arcs of the type utilizing rotating electrodes.

Patent GB-169684-A (GB)
Abstract: 169,684. Western Electric Co., Ltd., (Assignees of Mills, E. H.). Sept. 25, 1920, [Convention date]. Automatic exchange systems; metering and coin-freed systems. -The building-up of the automatic connection to the wanted line proceeds to a certain stage and is then arrested unless or until the calling subscriber has deposited a coin or operated his meter. In the system illustrated, the impulse transmitter S records the wanted number on a register controller represented by the dotted rectangle at the bottom of the Figure. The building-up of the connection proceeds until the tens selection has been completed, and the sender sequence switch then moves to its 14th position. If the calling subscriber has not yet deposited a coin, a relay 26 is energized over a back contact of a relay 35 and opens the fundamental circuit so as to prevent the units selecting operation. When the subscriber deposits a coin, one side of his line is grounded through a high-resistance polarized magnet 37, unbalancing the relay 35, which opencircuits the relay 26 so as to allow the connection to be completed. Fraudulent attempts to get a free call by directly grounding the line wire are defeated by a marginal differential relay 36, which responds in these circumstances and closes another circuit for the relay 36. On the other hand, in party-line systems in which the callbells are connected between ground and one or other line w.re, if the subscriber connects his line to the grounded bell wire the resistance of the bell is too high to allow the relay 35 to become energized. The polarized magnet 37 serves for collecting the coin at the end of a conversation, or, in the case of an unsuccessful call, for refunding the coin or cancelling the operation of the meter.

Abstract: 1334473 Protective clothing SOC LA CALHENE 13 April 1972 [15 April 1971] 17130/72 Heading A3V Protective clothing for an operator 6 working in a hemetic enclosure 1 comprises a garment having two walls, the inner wall 7 to contact the operator 6 and an outer wall 4 forming an exterior of the wall 2 of the enclosure 1, the two walls forming between them an inflatable zone which is fed with air from a supply line 8, the inner wall 7 having porous zones 13, 14, 15, 16, 17 through which air passes to the interior of the garment the flow of air being controlled by an adjustable elastic band 12 and the operator's hips past which the air escapes, and the garment being completed by a transparent helmet 9 and replaceable gloves 10. The clothing is described as being of use when the pressure in the enclosure 1 is above atmospheric pressure, but it may also be employed in cases where the pressure in the enclosure is less than atmospheric, the elastic band being arranged to seal around the operator's hips and a valve being provided to allow leakage of air from the interior of the garment into the enclosure 1. The porous zones 13 to 17 may be provided as apertures in the inner wall 7 or as uncoated zones in a plastic coated cloth. As a further alternative the inner wall 7 may be entirely of close-woven cloth. The inflation of the inflatable zone may be limited by interconnection of the walls 4, 7 at a number of places, e.g. by weld lines. In a further alternative embodiment the clothing entirely envelopes the operator's body and the clothing outer wall is extended by a flexible wall banding an access passage through which the operator can get into the clothing, and which is deformable to allow him to move about in the enclosure.

Abstract: 1,085,622. Winding webs. FRANK W. EGAN & CO. April 23, 1965 [Oct. 13, 1964], No. 17186/65. Heading B6B. In a turret web winding machine, Figs. 1 and 6 (not shown), the web 152 passes between a pair of feed rollers, 33, 38, over a spreader roller 52, around a driven lay-on roller 48 and is wound on to a driven core 150 supported in a two-arm, turret 16. The lay-on roller 48 is supported by a pair of arms 46 pivoted about an axis 45, the roller 48 having a counterbalance 49. The lay-on roller 48 is pneumatically urged by pressure cylinders 51 against the core 150. Longitudinally web slitters 153a or 153b may be provided. The speeds of the nip rollers, lay-on roller and core are adjustable relatively to vary the wind-up tension, i.e. compactness of the web roll. Web cut-off and transfer mechanism.-As the diameter of the web-roll approaches the required amount, the turret is rotated through 180 degrees to the position illustrated in Figs. 1 and 9 (not shown). In this position the web passes around the lay-on roller 48, around a new core 151 now in contact with the lay-on roller and continues to be wound on to the nearly completed web roll 150. At this point the cutoff and transfer mechanism is lowered into the bight between the web roll and the new core, Fig. 3, whereupon the web is severed and transferred to the new core by a blade moving into and out of contact with the web with a snap action. Normally pawl 135 is latched to arm 123, Fig. 4 (not shown), and when cutting is to take place lever 102 is rotated clockwise, thereby causing compression of spring 130 and movement of the rod 132 so that the nuts 138 move towards and are ultimately arrested by the block 127. Further rotation now rotates the pawl 135 to unlatch the arm 123 which rotates rapidly due to the expansion of the spring 130 to cause the sudden projection of the serrated knife 118 beyond the edge of the holder 117 to sever the web. Reversal of the rotation of the arms 102 then returns the mechanism to the position illustrated in Fig. 4 (not shown).
